Number of compute units on BXM-4-64

Using OpenCL (driver: I see that for BXM-4-64 the number of compute units is 1.

As determined by clGetDeviceInfo on the CL_DEVICE_MAX_COMPUTE_UNITS parameter.

Is this number correct? Does it really have only 1 unit?

Hardware: TH1520 SoC on Sipeed-PI4A.

Hi bram,

Thank you for your message.
Let me confirm the configuration from the spec documents and also with the right department and get back to you.

Best Regards,

Hi Bram,

Yes. What you are seeing is right. In PowerVR terminology we refer compute units as USC (Unified Shading Clusters ) and BXM - 4 - 64 has 1 USC.

Kindly let us know in case you require any further clarification.

Perhaps it’s the β€œ64” that Bram is interested in?
